A 10,000-Subscriber YouTube Channel Earns ¥30,000/Month in Ads. Why Keep Going? "¥100,000 Sponsorships and My Own Products"

How much ad income does “a YouTuber with 10,000 subscribers” make? Published data answering that question with actual monthly figures and RPM (revenue per thousand views) is rare in Japan. The answer: about ¥30,000 a month on average. And that is in a genre with top-class ad rates. What makes this article worth reading is that, starting from that “disappointing number,” the author goes on to disclose the full revenue structure, what a creator actually lives on.

The published numbers

Actual monthly figures — nine months of history

Lining up the monthly data he published gives a clear picture of what ad revenue really looks like.

Two facts are buried in this table. First, in five of the nine months he posted nothing, yet revenue never dropped below the ¥20,000s. Past videos keep getting watched via search and recommendations, the nature of a stock-type medium. On the other hand, in the months when posting resumed (December–January, May–June), views and revenue clearly lift. Stock alone means a plateau; growth requires input. YouTube’s character, sitting midway between flow and stock, is confirmed here in actual figures.

The business in outline

Shogo is a freelance web developer who runs a YouTube channel sharing his practical professional knowledge. He began working on it in earnest in January 2020 and grew from 300 subscribers to 10,000 over about a year and a half. Even though web development/freelancing is a genre with top-class RPM, ad revenue at the 10,000-subscriber mark hovered around ¥30,000 a month. He states plainly that it is “pocket-money level.”

His tactics for sustaining RPM are concrete, too: post videos over 8 minutes long, below 8 minutes, multiple mid-roll ads cannot run during the video and revenue efficiency drops. Even so, RPM is ¥800–1,200 per thousand views, i.e. roughly ¥1 per view. Several times the RPM of an average genre (around ¥100–300), favorable conditions, and still this absolute amount.

The real revenue lies “outside the ads”

What makes this record interesting is that it dissects YouTube’s revenue structure. Ad revenue (¥30,000/month) is proportional to views, and even in the highest-rate genre it stays at this level. Corporate sponsorships run about ¥100,000 per video, and even at 10,000 subscribers more than one inquiry arrives per month. He reveals, with screenshots, that one inquiry even came with a “¥2 million budget.” Amazon Associates brings in around ¥10,000 a month, which he positions less as affiliate income per se than as a traffic channel into his own blog.

And then there is the different order of magnitude: his own products. Sales of his self-made course, a “coding practice assignment built from design comps”, reach tens of times his ad revenue. In other words, this channel functions not as “a medium that earns from ads” but as a customer-acquisition engine that builds trust in order to sell his own products.

Subscribers grew — and revenue shrank

The follow-up numbers he appended are telling. Subscribers grew to about 14,500, but monthly views fell to 16,000. At an RPM of ¥1,000, ad revenue is about ¥16,000 a month, half the level at the 10,000-subscriber mark. What determines ad revenue is not subscriber count but that month’s views. Subscribers are less an “asset” than a “prospect list that gives new videos initial velocity.” If posting slows, ad revenue shrinks no matter how many subscribers you have, a quiet refutation of the conventional wisdom that ties channel size directly to income.

What can be learned here

The notion that “10,000 subscribers = great income” is an illusion, at least for ad revenue. A measured ¥30,000/month in the highest-rate genre implies that an average genre (RPM ¥100–300) would yield a few thousand to ten thousand yen a month on the same views. The gap with the gadget channel earning ¥166,000/month at 10,000 subscribers is the gap in the product of views times rate.

The correct P&L for YouTube is computed across three layers: ads + sponsorships + own products. Ads alone fall far short of web development’s practical billing rates, but viewed as “total income via the channel” including sponsorships and products, the ROI of publishing holds up. This is the same playbook as Hitode’s “individuality is the key”, using media as a trust engine.

Caveats in reading this published data

What is disclosed goes only as far as actual ad-revenue figures. Sponsorship and own-product income remain at the level of “¥100,000 per video” and “tens of times the ads,” so total monthly income cannot be computed. Production time and editing costs are not shown either, so hourly efficiency cannot be verified. Also, “more than one sponsorship inquiry per month” is a property of a B2B-leaning genre whose viewers are businesses and people with purchasing power, the same audience size in an entertainment genre offers no grounds to expect the same rates.

Conditions for replication

The conditions under which this model works narrow down to three: having a sellable professional skill (the raw material for content), being in a genre whose viewers have purchasing and commissioning power (the source of sponsorship rates), and having something of your own to sell beyond ads. Put the other way: reach 10,000 subscribers in a genre with no own products and no sponsorship demand, and all you get is the left edge of the table above, ¥20,000–40,000 a month in ad revenue. The question that comes before “should I start YouTube” is “do I have a business that can use it as a customer-acquisition engine.”
